Removing regular expression from string

Question

I have the following string:

/home/user/Documents/something/

I'd like to remove the */ part at the end of it. In this case this is something/. How can I achive that with java?

Try this I have tested in regularexpressplanet.com /+[a-z]+/$ — Pragnani Kinnera

You don't need regex to do this, below is a non-regex solution using String manipulation methods:

    String s = "/home/user/Documents/something/";
    String sub =s.substring(0, s.lastIndexOf("/"));
    System.out.println(sub.substring(0,sub.lastIndexOf("/")+1));

It's almost fine, but it removes "\something\" instead of "something\" like it should.

You can use the following code. It will remove the last past from your String :

        String str = "/home/user/Documents/something/";

    Pattern pattern1 = Pattern.compile("(/.+?/)(\\w+?/$)");
    Matcher matcher1 = pattern1.matcher(str);

    while (matcher1.find()) {
        System.out.println(matcher1.group(1));
    }
